Debugging is an inevitable part of iOS development. While Xcode provides a powerful set of tools, knowing how to leverage them effectively can save you hours of frustration. Here are some quick tips to improve your debugging skills:
1. Use breakpoints wisely
Breakpoints are your best friend! use conditional breakpoint Stop execution only when certain conditions are met. example:
if user.age > 18 {
print("User is an adult") // Set a breakpoint here for debugging.
}
Right click on the breakpoint and add a new condition, for example user.age > 18.
2. Using LLDB instructions
Xcode’s debugger (LLDB) is powerful. Use commands such as po to print objects, or bt to track call stacking. For example: (lldb) po viewController.title
3. Enable view debugging
When debugging UI issues, Xcode’s view debugging tools let you inspect and manipulate your application’s view hierarchy on the fly. Access it via Debug > View Debugging > Capture View Hierarchy.
4. Effectively analyze logs
Use Xcode’s console filters to quickly find specific logs. Add custom log tags, for example [DEBUG] or [ERROR] For better classification.
5. symbolic breakpoint
Establish symbolic breakpoints to capture specific function calls, such as viewDidLoad() or applicationDidEnterBackground(). This is useful for debugging application lifecycle issues.
